Abstract

A new Chrysanthemum plant named ‘Sycass Bron’ particularly distinguished by the greyed-orange colored inflorescences, medium green foliage, good mounding habit and a natural flowering season of mid September.

Description

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘Sycass Bron’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘Sycass Bron’.

‘Sycass Bron’ is a product of a planned breeding program. The new cultivar has greyed-orange colored inflorescences, medium green foliage, good mounding habit and a natural flowering season of mid-September.

‘Sycass Bron’ originated from a hybridization made in October 2005 in a controlled breeding environment in Tenjo, Columbia. The female parent was an unknown variety, as several small seed lots were bulked together when that generation was sown.

The male parent of ‘Sycass Bron’ was identified as ‘Cyclops’, an unpatented variety with a smaller and darker flower color, more disc florets, a more spreading plant habit and a natural flowering season that is 5-7 days slower. The resultant seed was sown in June 2005 in Alva Fla.

‘Sycass Bron’ was selected as one flowering plant within the progeny of the stated cross in the November 2005 in a controlled environment in Alva, Fla.

The first act of asexual reproduction of ‘Sycass Bron’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2005 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in December 2005 and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Sycass Bron’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Sycass Bron’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has been applied for in Canada on March 19, 2010 (No. 10-6890). ‘Sycass Bron’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Sycass Bron’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 a flowering potted plant of the new variety, in FIG. 2 a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant used for the photographs was about 14 weeks old grown in Monroeville, N.J. in an outdoor trial. One rooted cuttings grown in a nine inch pot with no terminal pinching of the apices. The photograph was taken in mid September 2010 in New Jersey.

The plant descriptions and measurements were taken from plants that were growing in an outdoor trial in Gilroy, Calif. The plants were grown in 1 gallon pots and were about 10-12 weeks old.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
